摘要： An improved air concentrator nozzle for creating an increased air exit velocity from an extension tube of a portable blower or blower/vacuum. The extension tube tapers from a larger, upstream end to a smaller, downstream end. The nozzle is inserted into the upstream end of the extension tube and drops until it protrudes outwardly from the downstream end of the extension tube. An interference fit between an exterior surface of the nozzle and an interior surface of the downstream end of the extension tube restrains the nozzle relative to the tube.

摘要： An apparatus for vacuuming up and chopping material such as leaves has a housing having a main chamber centered on an axis, an inlet port opening axially into the chamber, and an outlet port opening tangentially of the chamber. A rotor disk in the chamber centered on the axis has a hub at the axis and having an axially directed face provided with a predetermined number of radially and axially extending and angularly spaced vanes having outer edges. At least two and at most half of the vanes are provided on their outer edges with axially outwardly projecting chopper blades. A motor in the housing connected to the rotor disk at the hub rotates the disk about the axis and thereby draws the material in through the inlet, coarsely chops the material with the blades, and expels the coarsely chopped material with the vanes through the outlet port.

摘要： A yarn creel 20 includes vertical ducts 27 having openings 28 therein through which air is directed towards the upper surfaces of yarn cones 22 mounted on pins 21. Yarn drawn off from the cones 22 exits the creel 20 via tubes 23 whose entrance ends 24 are contained within a further duct 25, the duct 25 having slots 26 through which air is drawn from the interior of the creel 20. A fan 30 circulates this air so that it is re-emitted from the openings 28 in the duct 27. A continuous air stream is thus created over those points which are most susceptible to accumulation of lint. In an alternative embodiment, the yarn tubes extend with clearance through openings in the duct so that their entrance ends are disposed externally of the duct but close to those openings.

摘要： A blower vacuum attachment for use with a multi-purpose power tool having a motor for powering the attachment on the elongated tubular boom extending between the attachment and the motor through which a drive shaft extends. The attachment includes a tubular connector for attaching a blower housing to the tubular boom. The blower housing has an axial air inlet and a circumferential air outlet. An impeller oriented within the housing and driven by the drive shaft draws air into the axial air inlet and discharges air to the air outlet. An intake tube is affixed to the blower housing inlet and extends axially therefrom. A debris collection bag and a blower tube can be alternately attached to the blower housing air outlet so that the blower vacuum attachment could be used respectively as a vacuum or as a blower. The blower tube has an air inlet which is removably attached to blow the air out and an air outlet which is oriented generally adjacent the intake tube inlet for discharging air along a blower outlet axis which is spaced from and generally parallel to the central axis aligned with the intake tube. The blower tube air outlet is sized relative to the intake tube air inlet so that the air discharge velocity is substantially higher than the air intake velocity enabling the attachment to be used in the blower mode without removal of the intake tube from the blower housing or changing the way the user grasps the multi-purpose power tool.
